Can I make one other (possibly stupid) suggestion? if I understand correctly ... Can you perhaps have TWO ip addresses on the destination systems? alias the one on top of the other? Then DNAT from inbound interface A to target ip A DNAT from inbound interface B to tartget ip B and the unDNAT would handle more accurately? (or am I utterly off the wall here) and the reply from the target system to the firewall would not nessesarily come BACK from the ip it was sent to?
